Young's Modulus Young's Modulus is a measure of strength and stiffness. If you get a large force over a small area then you will get a large figure for stress. And a small extension divided by a large original length will give you a small figure for strain. Divide these numbers and a large modulus results, the material extends little for a large applied force. Steel has a large modulus, meaning that it is stiff and strong. A typical modulus for steel is 1100 Mpa, whereas cfrp, titanium and aluminium have modulus's of 2145, 900 Mpa and 400 Mpa respectively. This shows that although steel is not the strongest of the materials commonly used to construct mountain bike frames it is still very strong. Reasons why, although it is the strongest material, cfrp is not commonly used to construct frames will be discussed in the 'cfrp' section of this presentation. Elongation Elongation of...
